The 15% Minimum Tax Rate Rule on Foreign-Sourced Income in SG, HK & MY

A 15% tax-rate threshold appears in the foreign-income rules of Singapore, Hong Kong, and Malaysia, but it does not operate in exactly the same way in each jurisdiction.

Understanding the distinction is important when comparing foreign-sourced income exemptions across these three major Asian financial centres.

1. Singapore: A Foreign Headline Tax Rate Condition

Singapore's Foreign-Sourced Income Exemption (FSIE) for qualifying foreign-sourced dividends, foreign branch profits, and foreign-sourced service income requires several conditions to be satisfied.

One of these is the foreign headline tax rate condition.

The highest corporate income tax rate in the foreign jurisdiction from which the income is sourced must generally be at least 15% at the relevant time. Importantly, this is a headline-rate test; it does not necessarily mean that the particular income must actually have been taxed at 15%. Singapore also requires a separate subject-to-tax condition and a beneficial-tax-exemption condition.

For foreign-sourced dividends, for example, tax paid or payable can include both dividend tax and, in appropriate circumstances, underlying tax on the profits from which the dividend was paid.

2. Hong Kong: Part of the Participation Exemption Test

Hong Kong approaches the issue differently under its Foreign-Sourced Income Exemption regime.

For a qualifying MNE entity seeking the participation exemption for foreign-sourced dividends or equity-interest disposal gains, specific participation conditions must first be satisfied, including the relevant ownership and holding-period requirements.

There is then a subject-to-tax switch-over condition.

The relevant foreign income, or in the case of dividends potentially the underlying profits, must generally be subject to a qualifying similar tax in a foreign jurisdiction at an applicable rate of at least 15%.

The Hong Kong rules therefore use 15% as part of the test for whether the foreign income has been subjected to a qualifying similar tax.

Importantly, Hong Kong's 15% test should not be described simply as a universal requirement that the foreign income must have actually suffered tax at 15%. The legislation looks at the applicable foreign tax and rate under the specific participation-exemption rules.

3. Malaysia: A Different Exemption Framework

Malaysia also uses a 15% headline-tax-rate condition in certain foreign-income exemptions, but the rule must be considered in the context of the specific taxpayer and income involved.

For example, Malaysia's exemption rules for certain foreign-source dividend income can require the dividend to have been subjected to tax in the country of origin, together with a requirement that the highest headline tax rate in that country is not less than 15%, along with other applicable conditions.

However, this should not be generalized to mean that every Malaysian foreign-source income exemption has the same 15% test.

The treatment can differ between resident individuals, companies, LLPs, and other qualifying entities.

4. Why the 15% Threshold Matters

At first glance, Singapore, Hong Kong, and Malaysia appear to use the same 15% benchmark.

But the function of the threshold differs:

Singapore:

15% operates as a foreign headline tax rate condition within the FSIE framework.

Hong Kong:

15% operates within the participation exemption's subject-to-tax/qualifying similar tax condition.

Malaysia:

15% can form part of the conditions for particular foreign-source dividend exemptions, depending on the taxpayer
